Ceasefire Hierarchical Firearm Dataset

As part of the European Ceasefire project, we had the opportunity to access the weapons collection of the SNPS police forensics laboratory in Toulouse. We established a video acquisition protocol designed to capture firearms from a wide range of angles and applied it to record 45 firearms. Frames were then extracted from these videos to obtain numerous images from multiple viewpoints for each firearm model. In this version, we are publishing only 45 firearm models, organized into training and validation sets. This subset consists exclusively of images captured at the Toulouse Forensics Laboratory (France) and does not include any images from external or web-based sources. To access the full dataset covering all 260 firearm models, researchers must combine this version with the Firearms 14K dataset : 'https://github.com/jdhao/deep_firearm'本研究作为欧洲停火项目（European Ceasefire project）的组成部分，研究团队得以访问图卢兹SNPS警方法医实验室的武器馆藏。我们制定了一套多视角枪械（firearm）视频采集协议，并将其应用于45支枪械的录制工作。随后从采集的视频中提取帧图像，为每款枪械模型获取大量不同视点的图像样本。 本版本仅公开45款枪械模型，并将其划分为训练集与验证集。该子集仅包含在法国图卢兹法医实验室采集的图像，未纳入任何外部或网络来源的图像素材。 若需获取涵盖全部260款枪械模型的完整数据集，研究人员需将本版本与Firearms 14K数据集（链接：https://github.com/jdhao/deep_firearm）合并使用。
